Most processors have carry flags which they set on addition overflow, so
it's a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version.
Tested to compile on:
Architecture Compiler
x86 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
x86-64 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
x86-64 ILP32 GCC 4.9, GCC 5*, Clang 3.6*
IA-64 LP64 GCC 4.8
ARMv7-A GCC 4.9, Clang 3.6*
AArch64 Clang 3.6*
MIPS GCC 4.9, Clang 3.6*
MIPS64 GCC 4.9, Clang 3.6*
PowerPC GCC 4.9, Clang 3.6*
PowerPC 64 GCC 4.9, Clang 3.6*
SPARC Clang 3.6*
SPARCv9 Clang 3.6*
[*] supports the intrinsics
If the compiler does not offer a way to detect an overflow, we do it by
hand. For unsigned additions, that's easy, since the C++ language
specifies the behavior of the overflow. That's also the reason why this
code is implemented only for unsigned integers.
For the multiplication, if the compiler does not support widening
multiplications, we do it with a division instead. This is necessary for
GCC < 4.5 and compilers not compatible with GCC or MSVC.

The C++ standard says it must, but some badly-configured toolchains seem
to be lacking support.
In particular, for some 32-bit platforms without native support for
them, GCC implements 64-bit atomics via out-of-line functions in
libatomic. If that library is missing... well, then std::atomic 64-bit
doesn't work and we mustn't try to use it.
This was found when trying to compile Qt 5.6 for MIPS 32-bit:

In some cases it's not possible to use QT_HASH_SEED, specially when
we need to set the environment variable from inside the application,
as dynamically loaded libraries or plugins may create static QHash
instances. That would set qt_qhash_seed to a value different from
-1 and skip the env var value.
For those cases, and when we still want to set qt_qhash_seed, we
provide a way to enforce its value.
Auto-tests accessing qt_qhash_seed directly have been updated
accordingly. Usage in qdoc, uic and rcc has been left as is
for the time being.

Detection for most of them is free because we're loading the entire

I've also added the new GCC names so they can be used with
QT_FUNCTION_TARGET. The only two exceptions are "movbe" and "popcnt",
which are extremely restricted in use and we are not likely to have code
dedicated to using them.

Instead of trying to detect one bit and set another, let's just use the
bits from the x86 CPUID instruction on x86. This makes use of the full
64-bit space now.
Since MSVC doesn't like enums bigger than 32-bit, we have to store the
bit number instead of the actual bit value in the constant. For that
reason, I also renamed the constants, to catch anyone who was using them
directly, instead of through qCpuHasFeature.

This symbol will exist with different ELF versions, allowing us to know
which version of Qt a given library or application was linked
against. When this symbol gets used, automatic packaging tools will
extract the dependency. The trick here is that the application uses
qt_version_tag without knowing which version is current, but the linker
resolves it to the current version and records that.
For example, if this were used with Qt 5.5, RPM's find-requires on an
application using QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Whereas find-provides on QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(libQt5Core.so.5)(64bit)
libQt5Core.so.5(Qt_5.0)(64bit)
libQt5Core.so.5(Qt_5.1)(64bit)
libQt5Core.so.5(Qt_5.2)(64bit)
libQt5Core.so.5(Qt_5.3)(64bit)
libQt5Core.so.5(Qt_5.4)(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Therefore, automatic dependency resolution would have the information it
needs to conclude that the application requires Qt >= 5.5.

There is a qFatal in qmetatype.cpp that checks that the flags are the same.
There is a binary compatibility break because if any cause build with Qt 5.5
is loaded, this qFatal will quit the application, due to the change in
commit 54a09a4188:
Type flags for type 'QtMetaTypePrivate::QPairVariantInterfaceImpl' [1034]
don't match. Previously registered TypeFlags(0x103), now registering
TypeFlags(0x107). This is an ODR break, which means that your application
depends on a C++ undefined behavior.
This is a false positive since it is an internal type, the MovableType in
QMetaType is only being used for performance reason, it is perfectly fine
to change it.
This commit changes the qFatal to complain only about flags that could
only be caused by a binary incompatible change.

metacharacters (\b, \B, etc.).
This made the code that deals with QStringRefs not matching in behavior
with the corresponding code dealing with QStrings. For instance,
QString subject("Miss");
QRegularExpression re("(?<=M)iss");
re.match(subject.mid(1)); // doesn't match

Instead, actually adjust the pointer to the subject string so that
the behavior is identical. A broken test that relied on the
